We found a box of photography stuff in our house when we moved in. In 2007. We don't even own it anymore! But cleaning out for baby I found it again. Our attempts to return it to the owner didn't result in a response so they've been sitting around. I figure I might as well Craigslist them? But I don't know what they really are or what they're worth?

First the box says "lighting supports" on the box and "double ball joint head with cam PL". The other has nothing on the box but says de pixilation filter on the pamphlet inside. Are these sell-able? Any idea what to charge?
